In similar figure, the ratio of corresponding sides are always equal.

so,

Hi! I hope you're enjoying your day!

30 and 12x have a few common factors.

Both 30 and 12x are evenly divisible by

3 (30÷3=10, and 12x÷3=4x)

6 (30÷6=5, and 12x÷6=2x)

Hence, the common factors of 30 and 12x are

[tex]\boxed{\boxed{\bold{3\;and\;6}}}[/tex]

Hope everything is clear.

Answer:

3 & 6

Step-by-step explanation:

Determine a common factor. A common factor is 2.

Divide each term by the common factor and write the results of the division in parentheses, with the factor out in front.

Determine whether you can factor out any other terms.

Simplify the answer.

Answer:

B

Step-by-step explanation:

the perimeter (P) of a rectangle is calculated as

P = 2l + 2w ( l is the length and w the width ) , then

P = 2(3[tex]\sqrt{15}[/tex] ) + 2([tex]\sqrt{15}[/tex] ) ← distribute both parenthesis )

   = 6[tex]\sqrt{15}[/tex] + 2[tex]\sqrt{15}[/tex]

Using it's concept, it is found that there is a 0.4 = 40% experimental probability of the next player drawing a white token.

A probability is given by the number of desired outcomes divided by the number of total outcomes.

In an experimental probability, these number of outcomes are taken from previous trials.

In this problem, in the first 10 draws, 4 resulted in the player drawing a white token, hence:

p = 4/10 = 0.4.

There is a 0.4 = 40% experimental probability of the next player drawing a white token.

Answer:

R90

Step-by-step explanation:

120 hats sold and each = $0.50

0.50 × 120 = R60 (all the baseball hats cost)

50% of 0.50 = 0.25

0.25 × 120 = 30 (markup price)

60 + 30 = 90 ( total received for the sales)

Answer:

x = 4.46

Step-by-step explanation:

1. First, isolate the x. Subtract 2.9 from both sides of the equation to get x = 4.46

Answer:

x=7 and y=4

Step-by-step explanation:

I will use the elimination method:

Since the co-efficient of both y's are the same number but different signs we add the 2 equations to eliminate the y:

3x + y =25
+     +     +

2x - y = 10

Simplify:

5x=35

Divide both sides by 5:

5x÷5=35÷5

Simplify:

x=7

Substitute this into either equation 1 or 2 ( I chose 1):

3(7) + y = 25

21 + y = 25

Subtract 21 from both sides and simplify to get y:

21+y-21=25-21

y=4

Therefore x=7 and y=4

Step-by-step explanation:

A convergent series is a series whose partial sums tend to a specific number or a limit.

Example: [tex]3+1+\frac{1}{3}+\frac{1}{9}+.~.~.[/tex]

This is because a series is convergent if

[tex]-1 < r < 1[/tex]

where r is the common ratio

and for the question above

[tex]r=\frac{1}{3}[/tex]

A divergent series is a series whose partial sums do not approach a limit. Divergent series typically go to positive infinity, negative infinity, or don't approach a specific number.

Example: [tex]4+12+36+108~.~.~...[/tex]

This is a divergent series because the common ratio is;

[tex]r=\frac{12}{4} =3[/tex]

Quadratic formula: [tex]\frac{-b +-\sqrt{b^{2} - 4ac } }{2a}[/tex]

Step-by-step explanation:

We have -0.08t² + 1.6t + 2 = 9

Subtract 9 from both sides

-0.08t² + 1.6t + 2 = 9

                      - 9   - 9

-0.08t² + 1.6t - 7 = 0

We will have to use the quadratic formula

a = -0.08

b = 1.6

c = -7

[tex]\frac{-1.6 +-\sqrt{1.6^{2} - 4(-0.08)(-7) } }{2(-0.08)}[/tex]

[tex]\frac{-1.6 +-\sqrt{2.56 - 2.24 } }{-0.16}[/tex]

[tex]\frac{-1.6 +-\sqrt{0.32 } }{-0.16}[/tex]

[tex]\frac{-1.6 +\sqrt{0.32 } }{-0.16} = 6.464466[/tex]

[tex]\frac{-1.6 -\sqrt{0.32 } }{-0.16}=13.5355[/tex]

18% of $15 is $2.70

$15+$2.70=$17.70

Answer:

Tip: $2.70

Answer:

1 19/21

Step-by-step explanation:

1. Convert both mixed numbers into improper fractions:

2. Now we are doing 8/3 ÷ 7/5. We can use KCF to divide these fractions:

8/3 ÷ 7/5 → 8/3 × 5/7 = 40/21

3. Finally, convert 40/21 back into a mixed number: 1 19/21

The number of unit tiles needed to be added to the expression [tex]x^2 + 4x + 3[/tex] for making it perfect square trinomial is: Option A: 1

If a polynomial p(x) can be written as:

[tex]p(x) = [f(x)]^2[/tex]

where f(x) is also a polynomial, then p(x) is called as perfect square polynomial.

Terms are added or subtracted to make a polynomial. They're composed of variables and constants all in multiplication.

Example: [tex]x^2 + 3x + 4[/tex] is a polynomial consisting 3 terms as [tex]x^2 ,3x , \rm and \: 4[/tex]

The given trinomial is [tex]x^2 + 4x + 3[/tex]

Since the tiles are added to be in unit and positive(1, 2, 3, or 4), thus, let it be denoted by z, then:

[tex]x^2 + 4x + 3 + z = (x+a)^2[/tex]

since z is added such that the specified trinomial becomes perfect square trinomial, and since its degree is 2, so it must be product of two linear polynomials, and since coefficient of x in given trinomial is 1, so we kept the coefficient of linear polynomial as 1

Now, expanding the obtained equation, and comparing the coefficients, we get:

[tex]x^2 + 4x + 3 + z = (x+a)^2\\x^2 + 4x + 3 + z = x^2 + a^2 + 2ax\\[/tex]

Thus, from comparison of coefficients of like terms and constants, we get:

[tex]2a = 4\implies a = 2\\3 + z = a^2 = 2^2 = 4\\z = 1[/tex]

Thus, the number of unit tiles needed to be added to the expression [tex]x^2 + 4x + 3[/tex] for making it perfect square trinomial is: Option A: 1

Cube facts:

Solving the expression.

[tex](\frac{1}{3} )^{3} \\ \\= > (\frac{1}{3})(\frac{1}{3} )(\frac{1}{3} )\\\\ = > \frac{(1)(1)(1)}{(3)(3)(3)} \\\\ = > \frac{1}{27}[/tex]

Conclusion:

The cube of [tex]\frac{1}{3}[/tex] in fraction form is [tex]\frac{1}{27}[/tex].

Step-by-step explanation:

B = 0.08 - 0.016N

N = 3 hours 15 minutes = 3.25 hours (= 3 1/4).

so, we get

B = 0.08 - 0.016×3.25 = 0.08 - 0.052 = 0.028
